WATER-CLOSET.

FJPECIFICATION forming part of Letters Patent No. 349,962, dated September 28, 1886.

Application filed August 14, 1886.

To all whom it may concern:

Be it known that I, JOHN UPRIOHARI), a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in ater-Closets, of which the following is a specification.

My invention relates to an improvement in siphon water-supply or flushing apparatus for that class of water-closets in which the natural head or flow of water is not sufficient for flushing purposes, the objects of my invention being to insure the wetting of the interior of the bowl of the closet when the seat is first occupied, and to provide for the perfect draining of the flush tank and pipes when the closet is notin use, so as to prevent freezing in cold weather.

In the accompanying drawings, Figure l is a view, partly in elevation and partly in section, of a flushing apparatus for water-closets constructed in accordance with my invention; and Fig. 2, an enlarged sectional view of part of the same.

A represents the bowl of the water-closet, and B the trapped discharge-pipe of the same, the closet having the usual vertically-yielding seat, D, which is connected by a rod, a, to

' the valve E in the water-supply pipe b, the

valve being so constructed that when the seat is depressed said valve will be opened and a flow of water through the pipe I) permitted, the valve closing to its seat and cutting off the flow of water when the seat D rises. The pipe 1: extends upwardly and communicates at the upper end with a tank or reservoir, F, the upper portion of the pipe Z) being enlarged in diameter for the reception of the lower portion of the long leg of a siphon-pipe, G, the upper portion of which, together with the short leg of the pipe, is contained within the tank F, the long leg of the siphon communicating at the lower end with the bowl of the water-closet.

In that portion of the pipe G which is contained within the pipe I), I form an opening,

'1', preferably in the form of a short nozzle, as shown, so that when the water first rises in the pipe I) a portion of the water will enter the pipe G and be directed to the bowl, so as to wet the interior of the same and prevent the excreta from adhering to the sides Serial No. 210,?57.

of the bowl. The water rises in the pipe b and in the tank F until its level is above that of the bend at the upper end of the siphon-pipe G, whereupon the water in the tank is discharged from the same through the pipe G into the bowl of the closet, so as to effect the proper flushing of the latter.

In siphon water-closets of this character which are used in exposed situations it is important that the water should be allowed to escape from the pipe I) and flushing-tank F in the event of the person who has used the closethappening to leave the same, and thus permit the closing of the valve E before the tank has been filled to such an extent as to permit the siphon to act to empty the same; otherwise the water remaining in the tank and in the pipe I) is liable to be frozen. I therefore provide the pipe 1) beyond the easing of the valve E with a drain-pipe, m, co1nniunicating with the discharge-pipe of the closet above the trap, so that when the valve is closed any water which may be in the tank F or in the pipe I) between the tank and the valve will be permitted to gradually drain therefrom into the discharge-pipe B of the closet, some of the water also entering the bowl of the closet through the opening i and pipe G, while the level of the column in the pipe I) is above said opening.

Although I prefer in carrying out my invention to locate the siphon-pipe G- within the upper portion of the pipe I), said siphonpipe may be outside of the pipe I), if desired, a special pipesueh as that shown by dotted lines in Fig. 1, for instauceserving to afford a communication between the pipe I) and the bowl of the closet. It should of course be understood that the aggregate discharging capacity of the opening 17 and pipe at is consid erably less than the volume oiflow through the pipe 7), in order that the proper filling of the tank F will not be interfered with.

I claim as my inVention 1. The combination of the water-closet, the "alved water-supply pipe, the elevated tank, the siphon-pipe through which the contents of the tank are discharged into the bowl of the closet, and a communication between the sup ply-pipe and the bowl independent of said siphon-pipe, all substantially as specified.
